oil

For a stable performance and longtime running of mud agitator, regularly lubrication of gear box is necessary.

Routine lubrication consists of checking gearbox oil level and oil condition and lubricating gearbox bearings at required intervals.

Before operation, liberate gearbox with L-CKE/P 220~320# worn gear oil (while ambient temperature of drilling site around -30~40; or with L-CKE/P 320~460# worn gear oil (while ambient temperature around 25~65. Verify that lubricant level in the gear box reaches the bottom of the oil level plug.

Bearings should be cleaned and re-greased on the same schedule as oil changing. After cleaning, fill bearings to one-third of their free volume.

After 100 hours of initial startup, clean gearbox inside, add new grease oil. Then lubricated at every 2500-hour interval.

GNZJ50 (5000HP) rig system running well in a CNPC jobsit.

It is a 6-tank mud system including following:

1. 3 units Shale Shaker each capacity of 140m3/hr
2. 1 unit Vaccum Degasser GNCQ360 which remove the cuttings in gas from the drilling mud to improve the efficiency of transfer pump.
3. 1 each Desander and 1 each Desilter
4. 1 unit High Speed Decanter Centrifuge GNLW363
5. Agitators to prevent the drilling mud sedimentation
6. Centrifugal Pump for transfering mud internal tank and charging to mud pump.
7. This ZJ50 rig mud cleaning system also equiped with poor boy degasser to prevent blowout.

GN Decanter Centrifuge are specifically built for oilfield drilling applications, both onshore and offshore drilling rig need the decanter centrifuge.  Adjustable operating parameters enable the Decanters to be employed for a wide range of solids control purposes in drilling fluid systems including.  Barite recovery from the active mud system or from surplus mud in storage.  Separation of drilled solids from unweighted muds.

Decanting Centrifuge is A machine for the continuous sedimentation of suspended solids from a liquid by the action of centrifugal force in an elongated rotating bowl.
Continuous unloading of solids from the bowl is made possible by a conveyor which rotates in the same direction as the bowl but at a slightly different speed.

PRINCIPLE COMPONENTS of the Drilling Decanter Centrifuge

1.  Bowl (or drum)
2.  Conveyor (or scroll)
3.  Gearbox
4.  Frame and collecting vessel
5.  Feed inlet and distribution

ADIPEC is said to be the largest oil show in Middle east and the third big one in scaned worldwide.

In 2012,more than 120 manufacturers over 350 people came to Abu Dhabi to attend the show.

One of the most attractive exhibitor is GN Solids Control,China top solids control and waste management specialist.They atracted many visitors and many clients have definite interest for cooperation.

Vacuum Degasser is one the important equipment for oil drilling mud system for separation the gas from drilling fluids to keep the balance of the mud.

GN have around 10 Vacuum degasser in stock for sale

GNCQ Series Vacuum Degassers that are able to service the needs of any application .It is usually fixed after the shakers. Each degasser effectively and efficiently removes gases from gas-cut mud, thus ensuring that the proper mud weight is pumped down hole. In doing so, the degasserss are able to aid in the prevention of potential blowouts. Unlike the traditional vacuum degasser, GNCQ vacuum degasser is a self-contained unit. The gas-cut mud is drawn into the degasser by a vacuum created by a regenerative vacuum without needing centrifugal pump .Moreover, GN degasser can act as a big agitator for the drilling mud, which helps the treatment for desander and desilter. GN also have Atmospheric/Centrifugal Degasser available as an alternative to the standard vacuum type degasser.
